本申请要求于2015年08月10日提交中国专利局、申请号为201520599136.9、发明名称为“一种立装式铣刀片”的中国专利申请的优先权，和于2015年08月10日提交中国专利局、申请号为201520599364.6、发明名称为“一种密齿式铣刀盘”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及超硬工具技术领域，具体涉及一种立装式铣刀片和一种采用前述立装式铣刀片的密齿式铣刀盘。
背景技术
铣刀是一种具有一个或者多个铣刀片的旋转刀具，通过各铣刀片依次间歇地切去工件的余量，主要用于在铣床上加工平面、台阶、沟槽、成形表面和切断工件等。为重复利用铣刀盘的刀盘本体，现有的铣刀盘多采用铣刀片和铣刀盘的组合结构。
目前的铣刀片多采用单头设计，这是因为：目前的铣刀片普遍采用夹紧定位的方式，假如在夹紧的部分设计刀头，夹紧部位可能会产生磨损，一定程度上影响铣刀的工作可靠性；
铣刀盘安装于铣床的主轴上后，开动主轴，随着铣刀盘的转动，安装于铣刀盘外缘的铣刀片即可进行铣削加工作业。传统的铣刀盘的基体往往采用单一的结构(铝合金结构)，在使用时间长或者使用频率大的情况下容易出现定位差或者加工偏差等问题，稳定性亟待改善；而且由于定位结构多为夹装定位的方式，在保证可靠性的前提下，能够安装铣刀片的数量不能进一步增加，加工效率的进一步提升受限。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行详细说明。
图1是本发明实施例中立装式铣刀片的第一立体示意图，图2是本发明实施例中立装式铣刀片的第二立体示意图，图3是本发明实施例中立装式铣刀片的第三立体示意图图4是本发明实施例中立装式铣刀片正视图。如图1-图4，本实施例中的立装式铣刀片包括刀片基体1和安装在刀片基体1上的双刀头结构，双刀头结构包括第一刀头2和第二刀头3；第一刀头2和第二刀头3均为铣削加工用刀头，所以本实施例中的铣刀片为可转位铣刀片。刀片基体1的中间区域具有安装孔11，安装孔11用于和第一锁紧螺钉6配合将立装式铣刀片安装在铣刀盘中。
如图4，刀片基体1在垂直于安装孔11轴线的截面大体为四边形截面，即刀片基体1截面的大体轮廓为四边形。第一刀头2和第二刀头3安装在四边形刀片基体1相对的两个顶点处。
根据实际铣削加工过程可想到，刀片基体1除具有连接第一刀头2和第二刀头3的作用外，还应具有支撑第一刀头2和第二刀头3的作用，以将第一刀头2或第二刀头3铣削材料表面时受到的冲击力传递至铣刀盘中。为此，刀片基体1 应具有支撑第一刀头2和第二刀头3的支撑部位。为保证铣削加工过程中第一刀头2或第二刀头3不发生晃动，刀片基体1还应当具有定位作用。
如图1-至图4，本实施例中的刀片基体具有第一侧面12和第二侧面13，第一侧面12和第二侧面13为刀片基体1位置相对的两个侧面，第一侧面12对应第一刀头2的后刀面，刀片基体1形成第一侧面12的部分与第一刀头2连接，起到支撑第一刀头2的作用；第二侧面13对应第二刀头3的后刀面，刀片基体1形成第二侧面13的部分与第二刀头3连接，起到支撑第二刀头3的作用。
具体的，第一侧面12具有第一刀头支撑面14和第一定位结构15，第一刀头支撑面14直接与第一刀头2的后刀面连接，而第一定位结构15则相对于第一刀头支撑面14向刀片基体1的内侧内凹。同样的，第二侧面13具有第二刀头支撑面16和第二定位结构17，第二刀头支撑面16直接与第二刀头3的后刀面连接，第二定位结构17则相对于第二刀头支撑面16向刀片阶梯的内侧内凹。
如图4，第一定位结构15和第二定位结构17大体位于四边形结构的刀片基体1的另外两个顶点处。实际加工中，第一定位结构15和第二定位结构17为去除刀片基体1另外两个顶点处材料形成的凹陷区域的表面。因为第一定位结构15相对于第一刀头支撑面14内凹，所以在铣削加工过程中，第一定位结构15不会作为第一刀头2的后刀面区域被磨损、定位精度不受加工过程影响。同样的，第二定位结构17相对于第二刀头支撑面16内凹，所以在铣削加工过程中，第二定位结构17不会作为第二刀头3的后刀面区域被磨损、定位精度也不受加工过程影响。如此，在切换第一刀头2和第二刀头3作为铣刀刀头使用时，第一定位结构15和第二定位结构17分别和安装孔11配套起到定位的作用，保证铣刀片的定位精度和定位稳定性。
本实施例中的立装式铣刀片为可回收铣刀片，第一刀头支撑面14和第一刀头2的后刀面在同一平面，第二刀头支撑面16与第二刀头3的后刀面为同一平面。铣刀片的刀头磨损到一定程度需要修磨时，第一刀头支撑面14和第一刀头2的后刀面同时被修磨，而第一定位结构15的表面不被修磨；同样的，第二刀头支撑面16和第二刀头3的后刀面同时被修磨，而第二定位结构17不被修磨。因此，本实施例中的立装式铣刀片修磨成本较低。
本实施例中的第一定位结构15和第二定位结构17均为折面结构，利用折面 结构中不同的表面实现不同程度的定位，因此下文仅以第一定位结构15为例介绍本实施例中折面结构的具体形状。如图1-图3，本实施例中的第一定位结构15包括第一面A和第二面B，第一面A和第二面B不共面。其中第一面A用于和后文中密齿式铣刀盘中的第一定位面配合，第二面B用于和第二锁紧螺钉7的锥面配合调整铣刀片位置；在第二面B和第二锁紧螺钉7配合时，第一面A脱离与刀盘上的第一定位面47。
本实施例中第二面B为相对于第一面A向刀片基体1内侧倾斜的表面。如图2和图3，本实施例中的第一面A具有第一平面A1和第一曲面A2，第一曲面A2连接第一平面A1和第一刀头支撑面14；第二面B具有第二平面B1和第二曲面B2，第二曲面B2连接第二平面B1和第一刀头支撑面14。本实施例中，在第一刀头支撑面14和第一平面A1之间设置第一曲面A2为过渡曲面，可避免此区域出现局部应力集中的问题，防止刀片基体出现损坏。更进一步地，本实施例中第二曲面B2为轴线平行于安装孔轴线的圆锥曲面，第二曲面B2除具有减少应力集中的问题，还可增加与后文中第二锁紧螺钉7的接触面积。
图5是图4中G方向示意图，图6是图4中I方向示意图，图7是图4中H方向示意图。从图5中可看出，本实施例中的第一曲面A2也为轴线平行于安装孔轴线的圆锥曲面，只是第一曲面A2的锥度小于第二曲面B2的锥度。结合附图2、附图3和附图5，可想到，第一平面A1相对于安装孔11轴线的夹角为第一曲面A2的锥度，第二平面B1相对于安装孔11轴线的夹角为第二曲面B2的锥度。
从图6和图7可看出，本实施例中第二侧面13处的第二定位结构17和第一侧面12处的第一定位结构15相同，也具有第一平面A1、第一曲面A2、第二平面B1和第二曲面B2。另外，根据图4-图7可看出，本实施例中的铣刀片相对于安装孔11的轴线中心对称。
图8是图4中N-N截面示意图，图9是图4中K-K截面示意图，图10是图4中J-J截面示意图。从图8-图10可看出，本实施例中的安装孔部分区域为锥形孔，以便于和定位螺钉的定位面配合实现铣刀片的安装定位。
图11是图8中F区域示意图。从图11可看出，第一面A在刀片基体厚度方向的宽度为D。本实施例第一面的宽度D为刀片基体厚度的1/3～1/2。此外，从图11还可看出，第一面A和第二面B之间的夹角为α。具体应用中α可在10° ～30°，其中优选为12.5°。
在具体应用中，本实施例中的刀片基体1优选采用硬质合金，第一刀头2和第二刀头3优选采用聚晶金刚石(Polycrystalline diamond，PCD)或聚晶立方氮化硼(PolycrystallineCubicBoronNitride，PCBN)。
此外，本发明实施例中第一刀头2和第二刀头3的前刀面可设置断屑槽，利用断屑槽切断铣削屑。
除提供前述立装式铣刀片外，本发明实施例还提供一种采用前述立装式铣刀片的密齿式铣刀盘。
图12是本发明实施例中的密齿式铣刀盘示意图，图13是图12中L区域放大示意图。如图12和图13，本实施例中的密齿式铣刀盘包括刀盘本体4、立装式铣刀片5、第一锁紧螺钉6、第二锁紧螺钉7、动平衡调整螺钉8。
图14是本发明实施例中的刀盘本体示意图，图15是本发明实施例中刀盘本体中第一刀体和第二刀体爆炸示意图；图16是图14中M区域放大示意图。从图14-图16可看出，其中刀盘本体4包括第一刀体41和第二刀体42，第一刀体41和第二刀体42固定连接，第一刀体41通过刀柄和机床的驱动轴连接，第二刀体42用于安装立装式铣刀片5。
在密齿式铣刀盘铣削材料表面时，立装式铣刀片5作用在第二刀体42上的应力很大，为防止第二刀体42发生形变，本实施例中第二刀体42材质优选钢材等硬质材料；同时，为减小密齿式铣刀盘的重量，第一刀体41材质优选铝合金或钛合金等轻质合金；所以，本实施例中第一刀体41的硬度小于第二刀体42的硬度。
如图15，本实施例中第二刀体42呈圆环状，第一刀体41的底部具有轴肩结构，第二刀体42固定安装在第一刀体41的轴肩结构处。当然，在其他实施例中，第二刀体42也可直接与第一刀体41的端面配合连接，利用第一刀体41的端面作为第二刀体42的定位面。
如图14和图16，在第二刀体42中具有用于安装定位立装式铣刀片5的结构。具体的，第二刀体42的表面具有可装入立装式铣刀片5的刀片安装槽43,；刀片 安装槽43的底面具有用于和第一锁紧螺钉6配合的第一螺钉孔44；刀片安装槽43的侧面还具有第一定位面47；第二刀体42靠近第一定位面47的区域具有与第二锁紧螺钉7配合的第二螺钉孔45，第二螺钉孔45的轴线平行于第一螺钉孔44的轴线；此外，还具有与刀片安装槽连通的让空槽46。
将具有双刀头结构的立装式铣刀片5安装于刀片安装槽43内时，第一刀头2和第二刀头3中的一个凸出于第二刀体42，另外一个放置于让空槽46内且不与让空槽46的侧面接触。第一锁紧螺钉6穿过安装孔11将立装式铣刀片5固定于安装槽内；同时第一定位面47或第二锁紧螺钉7和立装式铣刀片5中对应的定位结构配合实现定位。
图17是图12中O-O截面没有安装第二定位螺钉时的示意图。如图17，在密齿式铣刀盘的加工精度要求不是特别高的情况下，立装式铣刀片5中的第一面A可直接贴合第一刀体41的第一定位面47，利用第一定位面47和第一锁紧螺钉6配合将立装式铣刀片5固定；此时第二锁紧螺钉7可不安装在第二螺钉孔45内，也可安装在第二螺钉孔45内但仅起到配重作用。
在密齿式铣刀盘加工精度要求特别高情况下，因为各种误差，各个立装式铣刀片5凸出于第二刀体42的刀头并不在同一平面上。此时可通过第二定位螺钉7和立装式铣刀片5中的第二面B配合调整立装式铣刀片5凸出于第二刀体42的尺寸，调平各个刀头。图18是第二定位螺钉和第二面配合时的截面示意图，如图18，第二锁紧螺钉7通过圆锥面和第二面B配合；如需调整时，使第二锁紧螺钉7向第二螺钉孔45内移动时，第二锁紧螺钉7的圆锥面向外挤压第二面B、使立装式铣刀片5整体向外移动；调整过程中，第一锁紧螺钉6应当先松开，使得立装式铣刀片可向外移动。
图19是本发明实施例中密齿式铣刀片部分剖面示意图。图19也示出了第二锁紧螺钉7和立装式铣刀片5中第二面B配合的情况。此外，从图19可看出本实施例中的密齿式铣刀盘还具有冷却液喷淋板48，冷却液喷淋板48与第一刀体41固定连接，并且与第二刀体42具有一定的间隙；冷却液喷淋板48上具有导向槽。冷却液经过第一刀体41的轴心输送至冷却液喷淋板48后，被导向槽推动加速离心而从间隙处甩出。
此外，本实施中的动平衡调整螺钉8安装在第一刀体41的外圆周面上。在安 装各个立装式铣刀片5、第一锁紧螺钉6和第二锁紧螺钉7后，如密齿式铣刀盘的重心不在轴心处，可通过改变各个动平衡调整螺钉8的位置将铣刀盘的重心调到轴心处。
以上对本发明实施例中的立装式铣刀片和密齿式铣刀盘进行了详细介绍。本部分采用具体实施例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的核心思想，在不脱离本发明原理的情况下，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
